Whenever I open an Office document on the OneDrive it asks me for my username and password. Why does it continue to ask me for them?

If you are trying to open an Office document from the OneDrive and it repeatedly asks you for your username and password, please note the following:

Microsoft requires that you login with your credentials to open an Office document from an online resource using WebDAV technology. However, instead of opening the file from there, copy it onto your computer and open it. This will ensure that you will have the entire file on your computer and it does come in handy if you are not able to access the OneDrive at a later time.
